Paravicini-Bagliani, Giacomo Scalari, Federico Valmorra, Janine Keller, Curdin Maissen, Mattias Beck, Jérôme Faist] Phys. Rev., B Open access ethresearch The coupling between the optical mode of an LC cavity and a magnetoplasmon is studied by terahertz transmission spectroscopy. The magnetoplasmons are created by etching a high-mobility two-dimensional electron gas into stripes. As a result, we identify three different regimes, depending on the plasmon frequency relative to the cavity frequency. We find a significant coupling to the cyclotron dispersion even in presence of screening of the electric field by the plasmon.
